Overview
INTEGRATED CIRCUITS DATA SHEET TDA7050T Low voltage mono/stereo power amplifier Product specification File under Integrated Circuits, IC01 July 1994 Philips Semiconductors Product specification Low voltage mono/stereo power amplifier GENERAL DESCRIPTION TDA7050T The TDA7050T is a low voltage audio amplifier for small radios with headphones (such as watch, pen and pocket radios) in mono (bridge-tied load) or stereo applications.
Features • Limited to battery supply application only (typ.
3 and 4 V) • Operates with supply voltage down to 1,6 V • No external components required • Very low quiescent current • Fixed integrated gain of 26 dB, floating differential input • Flexibility in use − mono BTL as well as stereo • Small dimension of encapsulation (see package design example).
QUICK REFERENCE DATA Supply voltage range Total quiescent current (at VP = 3 V) Bridge tied load application (BTL) Output power at RL = 32 Ω VP = 3 V; dtot = 10% D.
